详细内容
#####1. 将 JSONHelper.swift 文件加入工程
#####2. 自定义的解析数据模型需要实现 Deserializable 协议

internal struct Movie: Deserializable {
var name: String? // You can also use let instead of var if you want.
var releaseDate: NSDate?
init(data: [String: AnyObject]) {
name <-- data["name"]
releaseDate <-- (data["release_date"], "yyyy-MM-dd") // Refer to the next section for more info.
}
}
//使用
AFHTTPRequestOperationManager().GET(
"http://yoursite.com/movies/"
parameters: nil,
success: { operation, data in
var movies: [Movie]?
movies <-- data["movies"]
if let movies = movies {
// Response contained a movies array, and we deserialized it. Do what you want here.
} else {
// Server gave us a response but there was no "movies" key in it, so the movies variable
// is equal to nil. Do some error handling here.
}
},
failure: { operation, error in
// Handle error.
